Phenom II x2 555 be and galaxy gt630, what should i upgrade?



I have a phenom II x2 555 black edition oc'd to 3.7ghz

A Galaxy geforce gt 630 oc'd to 830mhz

biostar mcp6p m2+ motherboard

300w psu don't know the brand

compaq case which is awful

4gb's of ram

budget of £200
 


He would still need another PSU in order to put a decent video card in his current system, what i'd advise you to do OP is to save at least £400-500 for a decent system.

I just wanna know if I'm bottlenecking one or the other
